I discovered in my stash a stack of 5" squares, decided to try DP9 and was wondering if you could just pick up and sew any piece willy nilly scrappy or if it really made a difference in the color value/placement???? Any help would be greatly appreciated. I have the DP9 tutorial and she mentioned the placement of dark squares in center and four corners but I don't think I have enough dark/lights to do it this way. What do you wonderful, sharing, caring people think????
